The HiveMQ team is pleased to announce the availability of HiveMQ CE 2020.6.

This release provides plenty of great improvements and fixes:

✨ Improvements

• Improved memory usage when large payloads (10MB+) are published

🐞 Bug fixes

• Limited the size of the RocksDB log files
• Fixed a bug where the Prometheus extension did not return metrics under load
• Fixed automatic creation of a heap dump when HiveMQ runs out of memory
• Fixed an issue where message delivery stopped for one client with a persistent session after a HiveMQ restart
• The embedded artifact refers to the right hivemq-extension-sdk dependency version

You can find more information about and download the release on the GitHub release page. Additionally, we released a new version of the Prometheus Monitoring Extension (GitHub release page).

You can get the new embedded API as a Maven artifact from Maven Central, JCenter, or JitPack.

Be sure to check out the project on GitHub.

We recommend to upgrade if you are an HiveMQ Community Edition user.

Have a great day,

Silvio from the HiveMQ Team
